Bidding on items from pet treats to handmade benches and weekends at St. Simons, participants in the 12th Annual Silent Auction can enjoy themselves while helping the Humane Society carry on its mission to rescue animals and control their population.It’s always billed as the Silent Auction because most of the hundreds of items are auctioned that way, with offers written on paper. But the 6-8 p.m. event Saturday at Trinity Episcopal Church also features a 7 p.m. live auction of some major items, with Jack Orman slated to repeat as the leisurely paced, conversational auctioneer. “We’ve got a lot of good items to bid on out there, and we just want people to come and have a good time and learn a little bit about what we do and support our efforts for the animals of Bulloch County,” said Humane Society of Statesboro & Bulloch County President Kania Greer.Thanks to a $15 admission fee, those also give who look without buying.
